[QUOTE="sono, post: 15954667, member: 141834"] I think it's 2 fold 1st and most important is blower efficiency. Better design, 3 lobes vs 4, twists etc, also how much hp to spin the blower. Best case they were completely efficient and weighed nothing vs a gun safe that's hard to spin. 2nd Bigger is better. I say look at a 2.3 boost curve vs 4.0 liter boost curve. All things being equal the bigger blowers makes desired boost quicker due to slower rpms, and the boost never peaks or dips because you are at half it's limits in most scenarios. Using the same blower designs. I refer to 2 engines that both make 400hp/tq and spin to 7000rpm, but one makes the power much earlier in the rpm range. [/QUOTE]
